Abstract

Es ist ein im wesentlichen rohrföhrmiger oder zylindrischer Gasgenerator beschrieben und dargestellt (Fig. 1) der einen modularen Aufbau auf­ weist, eine günstige Herstellungs- u. sichere Einbauweise gestattet, insbesondere im Aufbau (z.B. am Armaturenbrett eines Kfz) für den Insas­ senschutz mittels von gezündetem Festtreibstoff generiertem Gas aufblas­ barem Gaskissen. It is an essentially tubular or cylindrical gas generator described and illustrated (Fig. 1) of a modular structure points, a cheap manufacturing u. safe installation allowed, especially in the construction (e.g. on the dashboard of a motor vehicle) for the Insas Protection by means of gas inflated from ignited solid fuel cash gas cushion.
